20 Claims. (01. 188-52) This invention relate'sto braking apparatus for ly-extending horizontal lever 23 which apcar trucks andmore particularly to a braking proaches the upper end of lever 18 and is cenmeans for usein car trucks of the type illustrated trally and pivotally link connected thereto as in my prior patent No. 1,831,714 issued November indicated at 24. At the opposite side of the truck 10, 1931, for Car trucks, 1 frame I secure a longitudinally directed brake An important object of the invention is to procylinder 25 the piston rod 26 of which is pivvide a construction disassociating the braking otally connected to the free end of transverselycylinder from the car frame proper and transextending lever 23 at 23b. It will be obvious that o ferring the mounting of this cylinder to the truck longitudinal movements of the rod 26 will cause frame, thus avoiding the use of long. brake rods oscillatory motion of brake lever 23 which and avoiding thewear occurring as a result of through the levers 18, 19 and link 21, is transconstant variation in distance between the car mitted to cause the longitudinal separation of frame to which the cylinder is ordinarily applied brake beams 16 and a consequent application of and the truck frame to which the brake levers are the brakes. Springs 2? connecting the beams applied. 16 tend to constantlymove these beams toward A further object of the invention is the proone another so that upon release of air from the vision of a construction compacting the braking cylinders the brake shoes will .move toward one mechanism to the greatest possible extent. another. e e to These and other objects I attain by the con- By use of a construction of this character the struction shown in the accompanying drawings number of connections necessary is reduced and wherein, for the purpose of illustration, I have the wear upon these connections likewise reshown a preferred embodiment of my invention duced. a and wherein: Since the arrangement employed is obviously a Fig. 1 is a plan view of a car truck embodying capable of a certain range of change and mod- 80 braking apparatus constructed in accordance ification without departing from the spirit of with my invention; my invention, I do not wish to be understood Fig. 2 is a side elevation thereof and as limiting myself thereto except as hereinafter Fig. 3 is a section on line 3-3 of Fig. 1. claimed.-
